XRP fees are designed to spike when transaction demand slightly exceeds network capacity. According to Ripple CTO David Schwartz, even a small overflow beyond the key threshold of 200 transactions per ledger can cause fees to jump quickly due to the exponential fee curve.
The mechanism works as follows: each rippled server estimates how many transactions can fit in the next ledger based on recent performance. When demand crosses the threshold, validators apply an exponential fee formula that prioritizes legitimate transactions by making spam economically impractical.
During recent fee spike events, users reported fees rising from the standard 0.00001 XRP to 0.001–0.01 XRP at peak — still orders of magnitude cheaper than Ethereum gas during congestion. The network returns to base fee levels once the congestion subsides.
Users can minimize exposure to fee spikes by setting a maximum fee tolerance in their transaction signing configuration. XRP wallets and libraries like xrpl.js allow configurable maximum Fee values that prevent accidentally signing overpriced transactions during congestion.
